ATTACENT FOR FOUNTAIN PENS.

Application filed June 10, 1921. Serial No. 76,412.

To all whom it may concern:

Be it known that I, EMIL Lenses, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Attachments for FountainPens, of which the following is a specification.

Fountain pens, as usually constructed, have their nibs or en portionsrigidly or permanently secured in the barrel, so that they are notreadily changeable.

When these pens are made sufioiently flexible for ordinary writingpurposes they are not adapted for making duplicate copies as with carbonsheets. The present invention relates to an adjustable attachment whichmay be readily applied to fountain pens for stifiening the nibs thereof,so that a single pen may be used for various purposes.

The objects of this invention are to provide an attachment forstifiening the nibs of a fountain pen; to provide a longitudinally andlaterally adjustable stiffener for fountain pens; and to provide such animproved construction as will be described more fully hereinafter.

In the accompanying drawings illustrat ing this invention;

Figure 1 is a side view of a fountain pen with my attachment appliedthereto.

Figure 2 is an enlarged detail view showing the attachment in section;

Figure 3 is a plan view;

Figure 4 is a cross section taken on the line 4-4: of Figure 3;

Figure 5 is a perspective view of the at tachment; and,

Figure 6 is a perspective view showing slightly modified form. I

As shown in these drawings, the attachment comprises a clip or band 7,which is adapted to fit around or engage with the pen .8 and its supportor feeding member 9. This clip is preferably split on one side, as.indicated at 10, so that it may be easily slipped over the parts withwhich it engages. The lower part of the clip may be made substan 'tiallyflat, as shown at 11, and is joined to the upper part 12 by an outwardlycurved portion 13, which increases the resiliency and permits the clipto be adjusted sidewise or laterally, so that it will fit fountain pensof different widths. This clip has a forwardly extending strip orprojection 14,

which is adapted to engage with the upper surface of the nibs, in orderto reinforce or stifien the same when desired. This pro'ection ispreferably curved a little more t an the pen, as shown at 15 so that theextreme end thereof will rest on the upper surface of the pen. Thepoint'of this projection is also preferably a little wider than the penpoint, so as to insure proper engagement therewith. In the modified formof construction, shown in Figure 6, the upper portion of the clip andthe central portion of the projection are cut away as shown at 16 toexpose the upper surface of the pen. This may be desired in connectionwith some pens in order to facilitate the-flow of the ink and to preventit from becoming dry between the pen and the attachment. A thumb piece17 is also provided for convenience in sliding the attachment back andforth. When the pen is to be used for manifolding purposes, as formaking carbon duplicates of bills, or the like, the attachment is pushedforwardly so that the point 14 will press against the nibs ofthe pen andstifi'en the same. In this manner an ordinary foun tain pen may be madesufficiently stifi, so that one or more carbon copies may be made. Whenthe fountain pen is to be used for oidinary writing, the attachment isdrawn back to the position shown in Figures 1 and 3 and the nibs willthen be unsupported and free to function in the usual manner.

Having thus described my invention, of which however, I do not Wish tolimit to the exact construction herein shown and described, except asspecified in the following claims. what I claim is:

1. The combination with a fountain pen having the usual barrel andfeeding member, of a clip adapted to engage with the pen and saidfeeding member, said clip having a forw'ardly extending projectionadapted to bear against the nibs'of the pen, the clip being slidablymounted and adapted to be adjusted longitudinally with respect to thepen.

2. The combination with a fountain pen having the usual support orfeeding member for the pen, of a clip slidably engaging with the pen andadapted to be adjusted longitudinally, said clip having a pointedextension bearing on the nibs of the pen, as and for the purposedescribed.

3. Anattachment for fountain pens, comprising a clip formed of resilientmaterial, and having a fiat under portion adapted to are 10 position.

engage with the supporting part of the pen, and a curved upper portionadapted to engage with the upper surface of the pen, said parts beingconnected by an outwardly curved portion, whereby the clip may beadjusted laterally for difl'erent sized pens, said clip having aprojection finger, the outer point of which is adapted to bear againstthe nibs of the pen when the clip is in adjusted meepo'a ed to engagewith the nibs of the pen to stiffen the same, the upper portion of theclip and the tongue being cut away to'form an opening, and a thumb piecefor said clip.
